Backup your device using iTunes (or iCloud) before using evasi0n. If something breaks, you’ll always be able to recover your data.

Please disable the lock passcode of your iOS device before using evasi0n. It can cause issues.

Avoid all iOS and iTunes related tasks until evasi0n is complete. Why not just enjoy a brief break from the computer to stretch your legs?

If the process gets stuck somewhere, it’s safe to restart the program, reboot the device (if necessary by holding down Power and Home until it shuts down), and rerun the process.

If you get an error on OS X 10.8 saying that evasi0n can’t be opened, control-click (or right-click) the app and on the revealed context menu, choose ‘Open.’ On the ensuing dialogue box, choose ‘Open’ as well.
